Anything interfering with another person's use or enjoyment of property.

• A. Nuisance
• B. Invitee
• C. Express license
• D. Trespasser

Answer: (A)

Nuisance is the concept being tested. It covers when actions or conditions created by one person unreasonably interfere with another’s use or enjoyment of their property. The interference must be substantial—not a minor annoyance—and can involve things like loud noises, strong odors, smoke, vibrations, or pollution that disrupts sleep, comfort, or the ability to use the land. The key point is the effect on use and enjoyment, not necessarily physical damage to the property.

The other terms describe different ideas unrelated to the core idea of interference with property use: an invitee is someone legally on the property to whom the owner owes certain duties of safety; an express license is permission to enter or use the property; a trespasser is someone who enters without permission. None of these define the broad notion of harming another’s use or enjoyment of property, which is why nuisance is the best fit.
